Postal directories
To correct addresses, assign codes, and presort your mail, the software uses
databases called postal directories. These directories are based on data from the
USPS. Because directory data changes and grows all the time, the USPS requires
directory updates at least every other month.
The following directories are available for use with the software.
The “x” in a directory’s file name represents a number that changes when the
directory format changes
City (cityxx.dir)
The City directory contains city names, states, and ZIP Codes, organized by state
and city. This directory is relatively small because it contains one record per
possible combination of city, state, and ZIP Code.
DPV (dpvx.dir)
DPV directories require 600MB of writable hard drive space. Do not rename the
DPV files. DPV directories are shipped monthly or bimonthly, your choice. The
DPV directories expire in 105 days and must be the same month as the National
ZIP+4 directory.
Delivery Statistics File
(DSF.dir)
The DSF directory is used for presorting to verify compliance with walk
sequence saturation and high density rate requirements.
eLOT (elot.dir)
Enhanced Line-of-Travel (eLOT) data is used to prepare carrier-route mailings
for Periodicals and Standard Mail. The software searches the eLOT directory
when you correct addresses that contain the CRRT and LOT or LOT_Order
fields. You need to use the eLOT directory only when you prepare carrier-route
mail.
Enhanced Street
Lookup (zip4us.rev
and zip4us.shs)
The Enhanced Street Lookup directories enhance the software’s street-name
lookup process. These directories make it possible for the software to find the
matching street name in the directories even when it can’t match the beginning
portion of the street name. With these directories, the software can compare the
last letters of the street name to find a match.
These directories are included in your Diversified Directories and are installed to
the NatlDirs folder.
Facility (facility.dir)
The Facility directory contains information about USPS drop-ship facilities, such
as drop-site keys, drop-site names, and drop-site delivery addresses.
GeoCensus
(TAgeox.dir)
GeoCensus directories are available with purchase of the GeoCensus option.
To assign GeoCensus codes, the software uses the U.S. Census Bureau’s TIGER
data during address correction. TIGER data is stored in 10 directory files that
total 1.5 gigabytes.
LACS Link (llk*.*)
LACS Link directories require 450MB of writable hard drive space. Do not rename
any of the files. LACS Link will not run if the file names are changed. LACS Link
